SVG drawings to AVIF: the smallest modern web format, nothing uploaded
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.Start with an SVG, a drawing stored as maths rather than pixels. It gets awkward because an SVG is code, so email clients, office documents, app stores and older phones routinely reject it. Turn it into AVIF and you get the smallest file of anything here at the same quality. AVIF is made of pixels, so the result no longer scales without blurring. AVIF is lossy, so a little detail is thrown away. The whole conversion happens inside this browser tab, so the picture never leaves your device.
Choose the SVG; AVIF is already set, and it can be written in Chrome and Edge.
Type the longest side in pixels into Draw the SVG at, anywhere from 16 to 4096.
Set Quality and keep it high, since AVIF is lossy and sharp edges in a drawing show the loss first.
Press Convert to AVIF, then Download the small .avif with its transparency kept.
Convert Image reads ten formats and writes seven. It opens JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF, ICO, SVG and HEIC, and saves as JPEG, PNG, WebP, AVIF, BMP, TIFF or ICO. Drop up to twenty files in and each row shows the new size beside the old one as it finishes.
Everything runs on your device. TIFF uses a reader loaded only when a TIFF arrives; HEIC uses a decoder loaded only when a HEIC arrives; an SVG is stripped of anything that could run or fetch and then drawn in an isolated image, at a size you choose. Writing WebP and AVIF depends on the browser, and the tool disables a format it cannot write rather than quietly saving something else. Limits are 20 files per batch and 50 MB per file.
Two jobs are refused on purpose. GIF is not written, because a good GIF needs a hand-chosen 256-colour palette and a bad one looks worse than the original. Camera RAW and Photoshop PSD files are not opened, because both need decoders far too large for a browser; export a JPEG or TIFF from your camera software, or a PNG from Photoshop, and bring that here. Nothing becomes an SVG: tracing pixels into shapes is a different job with different results.
The rest of the article, and all 8 questions about Convert Image, are on the Convert Image page.
Reading works for JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF, ICO, SVG and HEIC; writing works for JPEG, PNG, WebP, AVIF, BMP, TIFF and ICO. That is every pair those two lists allow, about sixty of them, and each pair has its own page with the target format already chosen for you.
Writing AVIF and WebP is done by the browser, and not every browser can. Chrome and Edge write both; Firefox and Safari often cannot write AVIF. A format this browser cannot write is disabled with a note naming the browsers that can, so nothing is silently saved in the wrong format.
Not here, and the page says so up front. Tracing pixels into shapes is a different job, done by Image to SVG on this site, and PSD files are now opened by PSD to PNG, which saves the picture and each layer. Camera RAW differs by manufacturer and needs a decoder too large for a browser; export a JPEG or TIFF first.
Twenty files per batch and 50 MB per file. Nothing is uploaded: the conversion runs in your browser, the TIFF and HEIC readers load only when one of those files arrives, and the converted files are built on your own device.
